TCS Arraying and Rigging  
This document explains how TCS loudspeakers can be arrayed and the reasons for the rotatable  
horns in some models. The TCS-122 and TCS-152 both feature Turbosound’s unique Dendritic high  
frequency waveguide. This can be rotated for two reasons:  
1. To allow a single speaker to be mounted horizontally but still retain the wider horizontal  
pattern, or  
2. To allow two or more speakers of the same to be arrayed with minimal interference  
The second application is explained here in detail.  
One of the benefits of the Dendritic waveguide is its exceptional coverage pattern and sharp edge-of-  
pattern cut-off as demonstrated in Flex Array. The sharp cut-off works either vertically or horizontally,  
depending on which way the horn is rotated.  
To explain this further, the TCS-122 and TCS-152  
feature exceptional pattern control either left/right or  
up/down depending on how the horn is rotated. This  
allows them to be arrayed with adjacent speakers  
without lobes or destructive interference. So the true  
arrayable benefit of the Dendritic is in the physical  
plane of the Dendritic device i.e. either left/right or  
up/down depending on orientation. The other plane  
of the Dendritic device functions in a similar way to a  
standard horn.  
The diagram here shows a TCS-122 with the horn in  
two possible orientations. The one on the left is the  
typical orientation, so for example the TCS-122/94  
model has a dispersion pattern of 90 degrees wide  
by 40 degrees in the vertical. The box on the right  
shows the box with the horn rotated to give 40  
degrees in the horizontal and 90 degrees in the vertical.  
So the speaker on the left has a very controlled vertical pattern, whereas the one on the right (the  
same speaker with the HF horn rotated) has a very controlled horizontal pattern.  
The TCS-122 and TCS-152 are both available with three dispersion options: 60° x 40°, 90° x 60° and  
60° x 40°. However note that only the 40 degree boxes benefit from being tightly arrayed, i.e with the  
sides touching. So in a cluster of two or three tight packed boxes, you should use either the 60° x 40°  
or 90° x 40° models and the horns should be orientated to give 40° dispersion in the horizontal plane.  
The TCS-122 and TCS-152 are double trapezoidal boxes and it is this feature, in combination with the  
rotatable horns that gives you the flexibility to build so many cluster options. The simple rule is that  
the side that is touching the adjacent speaker needs to be orientated to 40 degrees.  
The following options only apply to TCS-122 and TCS-152 models with Dendritic horns. The TCS-1561  
and TCS-61 use conventional horns.

cabinets where appropriate.  
Flying multiple cabinets  
When creating loudspeaker arrays the essential components are a pair of steel flyplates fitted to the  
sides of each flown cabinet, ensuring that all the rigging is steel-to-steel without any load being taken  
through the cabinets’ woodwork. Sets of joiners mate with the flyplates to connect one cabinet to the  
next adjacent cabinet.  
Following is a summary of the kits required and their component parts.  
FP-1 KIT 07G0335  
Consists of a pair or steel flyplates that fit both the TCS-122 and TCS-152 cabinets.  
1 x FP-1 kit is required for each cabinet that is to be arrayed.  
The FP-1 kit includes two flyplates, four M10 x 40mm bolts and four M10 spring  
washers.  
FP-2 KIT 07G0340  
Consists of a pair of steel flyplates for the flyable TCS-B15A and TCS-B15B  
subs. 1 x FP-2 kit is required for each sub cabinet. The TCS-B15A is  
dimensioned to fly with the TCS-122, while the TCS-B15B is dimensioned to fly  
with the TCS-152.  
The FP-2 kit includes two plates, four M10 x 40mm bolts and four M10 spring  
washers.  
With the flyplates installed on each box to be flown, now select the appropriate inter-cabinet couplers  
to connect the flyplates from one box to the flyplates of another.  
ICC-2H KIT 07G0345  
A pair of steel inter-cabinet couplers for linking two TCS-122 cabinets together.  
The couplers fit into the recesses provided in the flyplates and are secured using  
the M10 bolts and washers that are supplied with the FP-1 flyplate kits.  
ICC-3H KIT 07G0350  
A pair of steel inter-cabinet couplers for linking two TCS-152 cabinets together.  
The couplers fit into the recesses provided in the flyplates and are secured using  
the M10 bolts and washers that are supplied with the FP-1 flyplate kits.

ICC-4H KIT 07G0355  
A pair of steel inter-cabinet couplers for linking two TCS-B15 subs together.  
These can be either TCS-B15A or TCS-B15B versions, but in a cluster both subs  
should the same type. The couplers fit into the recesses in the flyplates and are  
secured using the M10 bolts and washers that are supplied with the FP-2  
flyplate kits.  
ICC-5H 07G0360  
A pair of steel inter-cabinet couplers for linking a TCS-152 cabinet to a TCS-  
B15B sub. Each box needs their respective FP-1 and FP-2 flyplate kits of course.  
The couplers are handed i.e. there are left and right versions. The couplers fit  
into the recesses in the flyplates and are secured with the M10 bolts and  
washers that are supplied with the FP flyplate kits.  
ICC-6H 07G0365  
A pair of steel inter-cabinet couplers for linking a TCS-122 cabinet to a TCS-B15A  
sub. Each box needs their respective FP-1 and FP-2 flyplate kits of course. As with  
the ICC-5H kit, the couplers are handed left and right. The couplers fit into the  
recesses in the flyplates and are secured with the M10 bolts and washers that are  
supplied with the flyplate kits.  
ICC-2V 07G0330  
A pair of steel inter-cabinet couplers for flying two TCS-122 or TCS-152 cabinets in  
a vertical column with one cabinet inverted to position the horns adjacent to each  
other. FP-1 kits are not needed to assemble this configuration; all that is required is  
one ICC-2V kit per hang.  
The kit includes two plates, four M10 x 40mm bolts and four M10 spring washers.

SB-61 07G0375  
The SB-61 is a swivel bracket used to hang the TCS-61 in standalone  
applications such as ceiling mounting in bars or clubs, or as an under-  
balcony fill. It consists of two parts: a ceiling plate and a speaker plate,  
allowing each part to be fixed individually and then assembled and  
angled to achieve the desired coverage.  
The SB-61 can also be used to hang the TCS-61 underneath the wider  
TCS-152 cabinet, with the facility to alter the downward angle.  
ICC-61 07G0370  
To hang the TCS-61 as a downfill speaker underneath the TCS-122, you  
will need a pair of ICC-61 inter-cabinet links fitted between the cabinets  
which positions the TCS-61 at an optimum angle to the TCS122.  
Following are some diagrams that illustrate these components and kits in action.  
In this example cluster three TCS-122  
cabinets are tight packed together using  
FP-1 flyplates on top and bottom and  
tied together with ICC-2H couplers. The  
horns are rotated to 40°h by 90°v and  
the cluster produces combined  
coverage of 120°h by 90°v. Pick up the

Important notes on rigging  
As with all rigging, the flying of these arrays should only be carried out by a professional rigger.  
The Turbosound rigging system has been designed and constructed to a high standard of safety, and  
tested to the most demanding of specifications. In order to ensure the highest safety standards, this  
information on the assembly and safe use of rigging accessories must be understood and followed.  
Only use Turbosound recommended rigging accessories, which are specifically designed for their  
intended purpose. Do not use Turbosound rigging with other types or brands of loudspeakers. This  
practice may compromise safety standards and Turbosound will not be responsible for damage or  
injury so caused. Do not modify the rigging accessories, or use them in a way other than that  
described in this user manual. Rigging components supplied as part of a complete assembly are non-  
interchangeable and must not be exchanged with the component parts of any other assembly. The  
component parts of a Turbosound rigging accessory must only be assembled using the fasteners and  
methods of assembly recommended in this guide. The use of fasteners and methods of assembly not  
specified or approved by Turbosound may result in an unsafe rigging assembly. Welding, or any  
other means of permanently fixing rigging components to each other or to cabinet fixing points is not  
allowed. Rigging assemblies must only be assembled using the appropriate parts and fixings as  
specified in this manual using the specific mounting instructions. Rigging components or assemblies  
must only be fixed to Turbosound loudspeaker cabinets using the cabinet fixing points, assembly  
methods and fasteners specified in this guide and the specific mounting instructions. When  
assembling the loudspeaker array ensure that all fixings are securely tightened before lifting the  
array.  
Secondary Safeties  
All loudspeaker clusters flown in theatres, studios or other places of work and entertainment must, in  
addition to the principle load bearing means of suspension, be provided with an independent, and  
properly rated and securely attached secondary safety. Only steel wire ropes or steel chains of an  
approved construction and load rating may be used as secondary safeties.  
Safety Inspections  
Carefully inspect rigging systems components and cabinets for defects or signs of damage before  
proceeding to assemble a flown array. If any parts are damaged or suspect, DO NOT USE THEM.  
Regular, more rigorous test and inspection of rigging components must also be carried out. Safety  
legislation and test and inspection requirements will vary from country to country. In most cases,  
annual independent test and inspection by a suitably approved and qualified inspector will be  
required. Users must ensure compliance with all applicable safety requirements. Turbosound  
recommends regular safety inspections and further recommends that a logbook be kept detailing the  
test and inspection history of each Turbosound rigging accessory. Always wear protective headwear,  
footwear and eye protection in accordance with local regulations. Anyone involved in flying ANY  
sound system should take note of the following advice:  
The rigging of a flown sound system may be dangerous unless undertaken by qualified personnel  
with the required experience and certification to perform the necessary tasks. Fixing of hanging  
points in a roof should always be carried out by a professional rigger and in accordance with the local  
rules of the venue. The house rigger and/or building manager must always be consulted.
